In 1985 he developed the first commercially feasible rendering software system called ARTS (Accelerated Ray Tracing System), based on ray tracing technique. This had become possible due to his development of a method for speeding up inherently slow ray tracing by several orders of magnitude for complex real-life scenes.

His concepts are being used in most commercially available ray tracing software.

His company, Integra, continued development of rendering software in close cooperation with the scientists of his homeland city of Szczecin, where the TBT (Turbo Beam Tracing) software was developed. This fact was the base of allegations in industrial espionage, because the counter-intelligence section of the Japanese police had found it impossible to believe that such an advanced software had been produced in Poland. This sensational spy story swept over Japanese newspapers in 1987 with titles like "The Shadow of the KGB in the center of Tokyo" (the headquarters of the company were in the Toshima-ku district of Tokyo). At these times, the Strategic Defense Initiative was the word of the day, and for some, the terms "ray tracing" and "ray casting" sounded very dangerous. It took several years to clear up the misunderstanding.
